Vor 5 Tagen · Die Delta-Distribution (auch δ-Funktion; Dirac-Funktion, -Impuls, -Puls, -Stoß (nach Paul Dirac ), Stoßfunktion, Nadelimpuls, Impulsfunktion oder Einheitsimpulsfunktion genannt) als mathematischer Begriff ist eine spezielle singuläre Distribution mit kompaktem Träger. Ihr übliches Formelsymbol ist δ (kleines Delta).
Vor 4 Tagen · Various steps to calculate the indefinite integrals are, Step 1: Normal indefinite integrals are solved using direct integration formulas. Step 2: Integrals with rational functions are solved using the partial fractions method. Step 3: Indefinite integrals can be solved using the substitution method.
Vor 3 Tagen · Integral representations. If the real part of z is positive then the digamma function has the following integral representation due to Gauss: [7] Combining this expression with an integral identity for the Euler–Mascheroni constant gives: The integral is Euler's harmonic number , so the previous formula may also be written.
Vor 4 Tagen · Integrals: An integral in mathematics is a continuous analog of a sum that is used to determine areas, volumes, and their generalizations. Performing integration is the process of computing an integral and is one of the two basic concepts of calculus.
